PRODUCT
SELECTION
The suitability of a gasket or gasket material in a given application is dependant on a number of factors:
Chemical resistance – consider process medium and cleaning agents;
Temperature – continuous and peak upper and lower limits;
Pressure
Flange material – configuration and bolt load;
Material Specifications and Approvals – for use with ‘Fire-safe’ applications, WRAS/WRC Potable Water,
FDA Compliance, etc.
Choosing the right product for the application can be a difficult and confusing task, indeed some materials may be
suitable, but only in certain thicknesses with given flange configuration. Some gaskets or materials will cover a wide
selection of sealing duties, but price constraints may necessitate the use of several types.
Some designers may have specified a ‘brand name’ rather than a specification, the reason for this must be established
before equivalents/alternatives can be proposed. Information solely gained from technical brochures can be misleading
as, for example, maximum temperatures and pressures of sheet materials may not necessarily be used simultaneously.
Pressure/Temperature charts are more accurate, but they are related to the thickness of the material – thinner materials
give better temperature and pressure properties.
This brochure offers designers and end users accurate information regarding a materials general properties and
behaviour for reference of existing products and an overview to assist specification of new materials or devices;
however should you have any doubt which product to select, please consult our Technical Team for advice.

RUBBER
AND
SPONGE
GASKETS
Rubber has found itself used in many industrial duties because it
provides and maintains elastic properties across a wide range of
process conditions and temperatures. As a specialist supplier of seals
and gaskets our development in rubber technology has remained progressive, with rubber lending itself so readily to so
many sealing applications. Whilst no single grade has all the desired properties, indeed some properties may only exist in
one type of rubber, by understanding the service conditions a suitable grade can generally be selected from stock or
achieved through careful compounding to a new specification.
Most natural and synthetic grades of rubber are also available in sponge form (cellular rubber) in both open and closed
cell grades. Open cell will absorb fluid, such as a car washing sponge; varying densities and materials of open cell can be
used for packaging, acoustic and sound insulation, filters and low pressure duty dust tight seals. Closed cell sponges do
not readily absorb fluid and make excellent gaskets in cut or strip form where lighter compressive loads and/or uneven
flange faces exist, to make effective low cost dust and low pressure fluid seals.
SEP can supply all rubber and sponge materials in:
Sheet/Roll – commercial, specification & diaphragm grades;
Gasket, Diaphragm, Strip or Die/Cad-Cam cut shape up to 100mm thick
Tape – to specified width & thickness with or without pressure sensitive adhesive backing;
Fabricated forms – segmented, dovetailed, vulcanised joints;
Extrusion and Moulded Shapes – see SEP brochure ‘Manufacturing in Rubber’.
Special application requests show our ultimate flexibility. Where a requirement
exists for a commercial or specification grade of rubber, thickness, hardness
and colour that is not readily available or economical; we have the ability to
mould the material in economic sheet, disc or ring sizes and then cut the
gasket within the same factory – and if required on the same day.

Cork-Elastomer Jointings are suitable for many fluid sealing applications in the automotive, engineering and
electrical industries. Cork-Rubber products hold up well under external environmental conditions and have the
advantage of minimal side flow compared to most rubber materials and generally possess better load distribution
across the sealing faces.
The majority of grades available utilise either Nitrile or Neoprene as the blended rubber binder; other blends, such as
Silicone and cross blends are available for specific process duties and cover obligatory industry specifications. Our sales
office will appropriately recommend the most effective material where such specifications are requested.
Most grades retain flexibility down to -25OC and can withstand maximum operating temperatures in liquids up to 110OC.
The ‘Chemical Suitability Guide’ below is intended only as a guide as the possible effect of elevated temperatures
needs to be considered when determining the compatibility of these products with a given chemical.

OP (Oil & Petrol) Paper Jointing is an economical cellulose fibre-based material
impregnated with a glue glycerine composition, or plasticised gelatine depending on the grade.
It is predominantly used in the automotive industry as a gasket material for carburettors, fuel and
oil pumps, gear casings and pipeline flanges. It has excellent resistance to fuels, oils and most organic solvents
and is ideal for use at low bolt loadings.
It has a maximum operating pressure of 8 to 10bar (depending on grade) and an operating temperature range of
-20OC to 120OC; limits of pressure and temperature should not be used simultaneously and are dependant on the
thickness of the gasket. Supplied in either sheet/roll or precision cut gaskets (maximum 1m wide) from 0.15mm,
0.25mm, 0.4mm, 0.5mm, 0.8mm, 1mm, 1.2mm, 1.6mm, 2mm or 3.2mm thick.
Engineering Felt is available in varying thicknesses, hardness and densities in both woollen and synthetic grades.
It can be supplied in sheet, strip or cut shapes for anti-vibration, sound & shock absorption, dust seals, oil seals,
wipers, polishing pads/wheels, filters and gaskets. Wool felts are used for wiping because their non-fray homogeneous
structure maintains constant performance during wear life and they can carry a liquid layer and distribute it evenly.
They are used for polishing because they are tough and resilient, wearing in such a way that the working surface is
constantly renewed. Because of their homogeneous structure wool felts make excellent filter media accommodating
high flow rates whilst offering good particle collection efficiencies. Long lasting resiliency under load offers application
suitability, in vibration isolators, padding & cushioning, shock absorption and gaskets.

Since the abolition of asbestos, the textile industry has adapted well in producing
high temperature textiles to cope with the varying demands of Industry today.
SEP offer various textiles manufactured from:
Aramid – 300OC
Glass – 550OC
Glass/Wire – 600OC
Silica – 1000OC
Ceramic – 1100OC
Most materials are available in varying forms:

Fabricated Parts
Dependant upon application many textiles are available with an array of coatings from Aluminium Foils to Rubbers
such as Silicone, Neoprene, Nitrile, EPDM and Viton. These coatings can often assist with service conditions,
handling, seal-ability and/or fabrication.
Fabricated forms such as flexible fabric connectors/compensators can be produced for the most challenging
of duties, offering resistances to high temperature, extreme cold, oils and chemicals, abrasion, or even just the
weather. The majority of fabrications are sewn in either kevlar, ptfe/glass fibre or stainless steel thread for high
temperature applications.
SEP also offer excellent quality, close tolerance, clean cut gaskets and shapes from high temperature resistant
millboards and high strength papers produced from mineral wool fibre sheets/rolls.

COMPRESSED SYNTHETIC FIBRE
JOINTING & GASKETS
Based on high performance reinforcing fibres with elastomeric binders, our sheet materials and
gaskets have been selected to cover a wide range of industrial, process and manufacturing
applications; providing sealing performance with a variety of specifications, covering an array of
temperature and service conditions. The careful selection of our business partners has established
SEP as a premier independent supplier and gasket cutter of superior industry recognised brands such as:
KLINGERSIL, NOVUS, FLEXITALLIC.
With heightened awareness of safety and environmental issues, reducing emissions from flanged assemblies has
become a major priority for industry. It is therefore crucial that the correct material is selected and installed appropriately,
to achieve a safe and reliable seal.
Material guidance from our ‘Select Range’ is available from the ‘Material Selection Directory’ on pages 10 & 11, and the
‘Chemical Resistance Charts’ on pages 19 to 22. Please consult our technical team at SEP for further options, or if any
doubts exist to a specific materials’ suitability.
Notes
Steam is a powerful hydrolyser and is one of the most difficult mediums for a gasket material to seal, as such additional
care should be exercised through product selection. Of particular importance is the degree of thermal or pressure
cycling expected in service, as the elastomeric binders within the materials can become brittle. For this reason we
recommend the use of our graphite sealing products on pages 13, 14, 15 & 18 for cycling steam duties.
Low Temperature service below -40OC will also harden the elastomeric binder in the
compressed fibre materials. To ensure safe service of these materials at low
temperatures we recommend that:
•
•
•
the gasket is fitted dry;
the gasket is fitted at room temperature;
the gasket is not re-torqued once in service.
Gasket Thickness is important and a given material should be selected as thin as possible, yet sufficiently thick
to accommodate surface imperfections and irregularities of the flanges. A thinner gasket requires less load to achieve
a tight seal, it can accommodate higher gasket loads and has better torque retention properties which helps
maintain a good seal throughout the lifetime of the gasket.
The width of a gasket, along with its thickness has a significant effect on the maximum
permissible gasket stress; we recommend a minimum thickness to width ratio of 1/5.
Good Storage conditions of our compressed fibre sheet and gaskets will
ensure a useful minimum life of 5 years. We recommend to store flat at:
•
•
•
room temperature below 25OC;
away from sources of UV/Natural light;
dry (humidity levels <60%).

GORETEX
PTFE (Polytetrafluoroethylene) is suitable for sealing duties with most chemical media across the whole PH range;
the exceptions being molten alkali metals, fluorine gas and any substances that may generate these at the operating
temperatures and pressures involved. It has an operating temperature range of -200OC to 250OC.
In addition to chemical resistance pure or virgin PTFE is well suited in FDA applications where process contact with
foodstuffs is required. Having a very low co-efficient of friction, PTFE can also be used for slide bearings, non-stick
applications and can be bonded to various substrates if the bonded surface is chemically etched.
Pure PTFE under certain process conditions is not always dimensionally stable and can creep or cold flow under load,
loosing gasket stress applied. PTFE Envelopes and Modified or Expanded PTFE materials have been developed to
suitably reduce these effects.
PTFE Envelopes can be manufactured to fit most soft cut gasket materials in all thicknesses and diameters, where the
recovery of the protected gasket/composite gasket compensates for the minimal creep associated with the thin wall
section of the envelope.
Whilst a multitude of fillers can be used, glass has evolved as the most common, improving both dimensional stability
and wear resistance; it is readily available in either 15% or 25% filled options. Care must be taken in selection as the use
of fillers can impair chemical resistance and in commercial, non-proprietary grades can often remove FDA compliance.
Modified (being reinforced or expanded) PTFE available from SEP, represents the latest generation of
multi-directional grade materials from leading brand manufacturers such as KLINGER (TopChem), NOVUS (Uniflon),
FLEXITALLIC (Sigma), WL Gore (Gore-Tex), GARLOCK (Gylon).

GRAPHITE
LAMINATE
Our range of exfoliated graphite products are designed for demanding, higher temperature applications typical of the
petrochemical and refining industries. Manufactured from high purity exfoliated graphite, the product is available with a
variety of metallic inserts that increase its tensile strength, load bearing capacity and improves handling characteristics.
Ultra high purity grades for the nuclear industry are also available.
Various proprietary brands such as KLINGER PSM-AS & SLS-AS, NOVUS Fi & Ti, SIGRAFLEX HOCHDRUCK,
FLEXITALLIC FLEXICARB RGS1, RGS2 & RGS4 are available with:
Foil reinforcement, normally one or more 0.05mm thick 316 stainless steel or nickel insertions laminated with the
graphite sheet by means of a super thin chloride free adhesive layer.
Tanged reinforcement, normally a tanged 0.10mm thick 316 stainless steel insertion mechanically bonded between
graphite sheet, resulting in a sturdy gasket material with excellent mechanical strength, capable of sealing higher
internal pressures than standard foil reinforced grades.
Cut tanged gaskets can occasionally leave sharp edges; therefore adequate care must be taken during handling,
fitting and removal.
Both grades are available from SEP in sheet or cut gasket form, with or without ‘Anti-Stick’ finish to a maximum sheet
size of 1.5M x 1.5M. Larger sized gaskets can, depending on service conditions, be successfully dove-tail joined.
Cut gaskets are also available with a 316 stainless steel eyelet which removes potential process contamination and
improves the gaskets’ blow-out resistance.

GRAPHITED CORRUGATED METAL
GASKET G-CMG (ELASTAGRAPH)
Elastagraph gaskets are made by infusing a seamless layer of flexible graphite at varying densities and thicknesses
over a corrugated metallic core; the standard core being 316 Stainless Steel, with other alloys available on request.
Elastagraph utilises a unique corrugated pattern which increases the depth of the groove and the pitch of the
corrugation. This greatly improves the gasket’s seal-ability over other corrugated designs.
The increased pitch and groove depth increase Elastagraph’s recovery or ‘spring back’ and reduces the surface area of
the gasket for a greater unit load at initial torque, as well as a lower minimum seating stress. This ensures maintenance
of bolt load during thermal cycling.
The proprietary production process allows the graphite to be applied without the ‘seam’ that is present in other gaskets
fabricated from flexible graphite sheets. Furthermore the inner diameter of the Elastagraph gasket is encapsulated by high
density flexible graphite providing total corrosion resistance and increasing seal-ability over traditional laminated designs.
Unlike other corrugated designs Elastagraph does not contain any adhesive that would normally contribute to bolt
torque loss.
Availability
ANSI 1/2” to 24” Class 150 & 300lb. DIN sizes 10,16,25,40 bar. Non standard sizes/special shapes available upon request.

SPIRAL
WOUND
GASKETS
Spiral wound gaskets are semi-metallic products designed for high pressure and temperature applications and where
vibration or flow rates are beyond the capability of conventional gasket materials. They have the ability to recover under
the action of fluctuating loads caused by process fluid pressure and temperature changes, flange rotation, bolt stress
relaxation and creep.
The gasket sealing element consists of a pre-formed ‘V’ metallic winding strip with layers of a softer, more compressible
material which, during compression, is densified and flows to fill imperfections in the flange surface when the gasket is
seated. The metal strip holds the filler, giving the gasket mechanical resistance and resilience.
Spiral wound gaskets can be manufactured from various filler materials and assuming an appropriately
rated metal winding strip is selected, the operating limits of available sealing materials are:

JOINTS
Metallic ring type joints (RTJ’s) are heavy duty, high pressure gaskets largely used in
offshore and refining petrochemical applications. The precision engineered solid
metal gasket provides an excellent mechanical joint, when used in conjunction
with precision machined flanges of the appropriate material and hardness;
the gasket material is typically about 30 Brinell less than the flange material.
Ring joints can be manufactured to API 6A, ASME B16.20 and BS7076
pt 2 standards and to customers’ own specifications.

The type R oval configuration is the original ring joint design and was followed by the type R octagonal which
offers more specific contact sealing areas. Both types can be used with flanges having the standard ring joint flat
bottom groove and hold off flanges by a specified amount, relying entirely on correctly applied initial bolt load for
their proper operation in service.
Metallic gaskets of varying designs and materials are available from SEP on short
lead times. These gaskets or seals can be as diverse as simple press cut soft
iron washers, tight tolerance compressor head rings in aluminium to exotic
copper valve seals.
RTJ with PTFE insert prevents build up of
debris in the annular space between outer
diameter of the ring and the bore
of the flange. Also reduces
turbulence as product
flows past the gasket.

METAL
JACKETED & SOFT
METAL GASKETS
FACED
Metal jacketed gaskets consist of a partial or full metal envelope,
covering a soft pliable core. The sealing filler provides good resilience
to aid sealing, while the metal jacket offers the suitable strength required for
higher pressure applications, fluctuating temperatures and protection from
corrosion of the core. Metal jacketed gaskets offer a relatively economical seal where
sealing faces are narrow; they can be produced in a variety of shapes, making them a good
option for heat exchangers with good, even flange surface finish (maximum 1.6um).
As well as Heat Exchangers metal jacketed gaskets are used in Vessels, Valve Bonnets, Pumps,
Autoclaves, Engines and Exhaust Systems.
Metal jacketed heat exchanger gaskets often consist of a sealing outer ring with integral partition bars; SEP recommend
(where possible) that the outer ring seals independently, with any partition bars welded in position and not
fabricated in one piece. Typical heat exchanger configurations are generally 3mm thick.

Soft faced metal gaskets are an alternative to metal jacketed where the requirement is for softer,
conforming sealing layers applied to the faces of a metal core. Whilst camprofile or corrugated gasket
upgrades may be considered, the cost of machined serrations may not be necessary or machining/corrugating
large rectangular shaped gaskets is impractical.
The cores are reusable after service, if appropriately cleaned, inspected and re-faced with new sealing material.
A typical gasket would be 3mm stainless steel, faced both sides with 0.5mm graphite.
SEVENTEEN
Specialised Engineering Products
CAMPROFILE
GASKETS
Camprofile gaskets consist of a metal core, with machined concentric grooves on each side, covered with a thin,
bonded soft layer of sealing material. The serrated metallic core is very effective for sealing in applications where high
temperatures, high pressures and fluctuating process conditions exist. They can be used without sealing layers, but
there is a risk of flange surface damage, especially at high seating loads. The sealing layers protect flange surfaces
from damage whilst offering excellent, conforming sealing properties when supported by the serrated metal core.
Camprofile gaskets are ideal for both standard pipe and heat exchanger applications; the metallic core and sealing
material is dependant on the service duty.
SEP recommend the use of graphite as the sealing material where possible; only in cases where graphite may cause
media pollution, is not chemically resistant or is outside recommended temperature limits should an alternative material
be selected.
Assuming an appropriate metallic core material is selected, the operating limits of available sealing
materials are:

and a maximum groove depth of 0.5mm, generally in one of the
following configurations:
‘LA2’
‘M20L’
‘LA1’
‘M18L’

‘M21LM’
Camprofile cores are re-usable after
service, if appropriately cleaned, inspected
and re-faced with new sealing material.
This is of particular advantage in the case
of heat exchanger gaskets.
